php动态数据点击表头部排序问题

Jun 23, 2016 pm 01:06 PM

想要实现点击列头进行排序,table中的内容为动态数据,表头输出固定,内容只有一行(一个tr)循环输出,网上找到的代码都是对固定数据进行排序的。求一份动态数据排序的代码。最好能写一小点代码方便理解。

只有一行,怎么展示排序的结果?

<table>      <tr>           <td onclick="sortData()" data-sort='asc' class='head'>表头</td>      </tr>      <tr class='data'>           <td>数据</td>      </tr></table>
Copy after login
Copy after login

1其实很简单,要是不考虑数据库负载,可你可以这样 给你个简单demo.
你可以用sortData()的js触发事件 ajax移步去请求数据库重新按你想要的顺序排列
注意后边的data-sort属性 这是纪录你当前排序的顺序
      function sortData(){     var sortString = $(".head").attr('data-sort');      //获取你的查询条件 和sortString     //ajax请求    $(".data").remove();//把以前的数据移除掉    //拼接数据 替换     }
Copy after login
Copy after login

原理就是异步请求查询数据后 凭借标签 替换现有页面标签

2.如果不想查询数据库 那么刻意根据data class 把所有的数据标签找到 然后用js进行排序后替换掉页面标签

无论怎么实现 你都要替换页面原排序的标签元素 这个是主要的

<table>      <tr>           <td onclick="sortData()" data-sort='asc' class='head'>表头</td>      </tr>      <tr class='data'>           <td>数据</td>      </tr></table>
Copy after login

嗯,谢谢提醒,我已经实现了,给表头添加了a标签,给定触发事件换参数查询数据库重新加载页面实现的。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
